Description

The invention relates to a device for bridging expansion joints on buildings, in particular road and bridge structures, as described in the preamble of claim 1 is.

EP 1 033 442 A1 describes a device for bridging expansion joints an oppositely offset arrangement of finger plates with overlapping ones Fingers - the same applicant - known, the finger plates interchangeable in the Structures anchored anchor profiles are attached, especially screwed. Through the high loads acting on these devices inevitably lead to damage on the finger plates, as well as on the fasteners. An exchange of damaged Parts turns out to be difficult in the known version because of the Anchoring in the building accessibility to the fasteners with tools is impaired. Therefore, it is often necessary to change the finger plates or the fastener is given, a high repair and cost because the substructure has to be completely or partially removed, which also longer-term traffic disruptions exist with such measures.

According to another solution known from the prior art, are for better accessibility Finger plates and substructure provided on freely cantilevered consoles, which allow the use of long screws protruding through the brackets and the nuts on the underside of the console are freely accessible. With this solution met the requirement for good accessibility to the replacement, though significant disadvantages are accepted. The manufacture of the consoles is the same of the extra long screws, very expensive. Furthermore, an enormously increased space requirement is required, which leads to a wider and costly design of the abutments for the structure of the Leads bridges. In addition, the distance between the bridge bearings and the transition construction increased. This in turn leads to the structural deflection caused by traffic to a limitation of the use of the finger plates, since every structural deflection leads to a growing out of the fingertips in the road level and thus to loss of comfort when driving over and increased wear on the chassis, especially the tires of road users.

Another problem arises when using a finger transition construction Bridges if porous asphalt layers are used as road surfaces. That in the porous asphalt layers penetrating surface water should be able to Drain the end of the structure to prevent frost damage. Frost damage occurs particularly often quickly open in places where the compaction of the asphalt layers during paving is made difficult by the immediately adjacent lane crossing. There are already several Solutions that solve the problem in the immediately before the road crossing a drain pipe is arranged which has slots in the direction of the asphalt layer. The disadvantage of this design is that the drain pipe cannot be cleaned and after some Time loses its function due to pollution. Furthermore, this design requires one elaborate, wider design of the connecting flange of the bridge seal at the carriageway crossing. The removal of the water in the scrapboard area is problematic because there are usually no further drainage pipes. The problem is that to solve if the substructure over the entire width of the road at short intervals with grooves lying directly under the cover plate in the longitudinal direction of the structure or channels is provided, which to the adjacent asphalt layer and the bridge gap are open. The water emerging from the asphalt layer is shared with the intermediate the surface water penetrating the finger plates into the drainage path of the transition initiated and discharged. The drainage grooves can be made from the bridge gap at any time cleaned and freed from the contaminations that impair the function.

In addition, a problem is known when bridging expansion joints, which in the inspection, maintenance and cleaning of roadway crossing constructions in finger construction occurs. The constructions are in the area of the bridge gap with drainage channels equipped that are mechanically connected to the substructure. The outside visible components of the carriageway crossing must be inspected at regular intervals checked for damage or malfunctions. This is made difficult since the drainage sheets are usually made of elastomer, but in any case of light-tight Material are manufactured and so the assessment only by means of artificial lighting can be done. The degree of pollution of the drainage tracks is from the bottom not recognizable, so the control must be done from the top, which creates a disability of the traffic is given by a partial decommissioning of the passability. This is to be resolved insofar as a material for the drainage tracks made of translucent, elastic material, e.g. clear soft PVC sheeting. Thereby the components of the roadway crossing constructions are easier to control in this area and the degree of pollution of the drainage tracks and thus the need for Cleaning easier to assess.

Another problem with the finger construction for bridging expansion joints occurs then when there is little space available in the longitudinal direction of the structure. Mostly it is available bridge gap large enough to accommodate the movements of the Supporting structure, but too small to accommodate cantilevered finger plates, so that Refurbishment and new equipment of such constructions with finger plates is difficult. A conversion of the structure and the abutment is usually associated with very high costs. A solution, on the other hand, is provided by finger plates, which are arranged so that, as with resting fingers, the fingers in operation, depending on the structure, partly the opposite substructure. The fingers should be designed that the overlapping part is thinner and so in contact with the opposite substructure comes, with a corresponding design of the underside of the fingers not static Represents impairment, since this corresponds to the occurring voltage curve can be conical towards the tip anyway.

Another, not inconsiderable problem when designing such finger constructions is the corrosion-protected version, that with coatings or coating is to be solved, taking into account that such coatings or coatings none may have a permanent negative influence on the pretensioning of the fasteners. Such an impairment occurs due to the shrinkage of the coatings or coatings and there is a decrease in the preload force of the screw connection this leads to premature failure of the screw connection due to fatigue fractures. this The problem has to be solved that, if necessary, on a coating in partial areas the construction and / or finger plates is omitted and instead a seal by filling the joints between the finger plates and to the adjacent ones Components with plastic grout that cures to a permanently elastic state becomes. The joints are filled after installing the finger plates and the fastening process by tightening the screw connections. No sealant can do this get between the finger plates and the steel substructure and thus becomes the specified preload maintain the screw connection. On the one facing the bridge gap Sealing between the finger plates and the substructure is difficult because the Access from below through the drainage track is blocked. One solution is milling of grooves parallel to the bridge gap in the finger plates or substructure, which in turn can absorb elastic sealants. This solution caused because of the required mechanical processing high cost. There is also a risk if the crowd of the applied sealant is too large that it is between the finger plates and the substructure penetrates and affects the preload of the screws.

A solution to this is given by the fact that at the top edge lies the one in the bridge gap Front of the substructure by means of a profile made of elastic material and an open, small duct is created for the substructure. This takes the plastic one Grout that hardens to a permanently elastic state. This mass is exaggerated introduced and pressed against them during the assembly of the finger plates, whereby sets the desired sealing effect. If a larger amount than intended in the channel is introduced, it increases its volume by deformation and prevents excess Material is pressed between panels and substructure. Because the elastic Profile only functions until the sealant hardens - similar to lost formwork - Has it, by means of an inexpensive assembly adhesive on the substructure be attached.

The problem of "corrosion" can of course also be solved by using corrosion-resistant materials, e.g. stainless steel, which will be solved however higher material and processing costs are incurred.

The object of the invention is to provide a device for bridging expansion joints To create structures with the expense of maintenance and replacement of parts of the Device is small.

This object of the invention is represented by the characterizing part of claim 1 Characteristics achieved. The surprising advantage here is that the arrangement a positioning means for the fastening means of the screw connection the dimensions the device for bridging expansion joints can be minimized because for Fasten the finger plate tools only from the freely accessible top of the device are to be used and thus both the initial assembly and a subsequent one Replacing damaged finger plates is simplified.

An embodiment according to claim 4 is also possible, which minimizes it.

A further advantageous embodiment is described in claim 5 because it has a high resistance to deformation for deformation-free absorption when tightening the fasteners resulting torque force is reached.

However, training according to claim 6 is also advantageous, because this makes the application extended fastening screws are made possible, which have an increased degree of expansion, so that the preload force of the screw connection is maintained even with alternating loads remains, which prevents fatigue fractures of the fastening screws.

However, training according to claim 7 is also possible, whereby a very simple and cost-effective manufacturing is achieved.

Ensure the advantageous training as described in claims 8 to 10 both a simple initial assembly and the accessibility for the exchange of the Fastening means a simplified maintenance and / or repair effort.

According to claims 11 and 12, an exact guide for positioning the fastening means, as well as the required anti-rotation device to apply the tightening torque reached.

According to the advantageous developments as described in claims 13 to 15, result variants for the formation of the receiving means and also the anchor profiles Adaptation to the available space, which means that retrofitting can also be carried out Devices for bridging expansion joints are possible.

Another advantageous training for the simplified manufacture of a guide arrangement for the fastener on the anchor profile characterizes claim 16.

According to the advantageous development as described in claim 17, internal ones Elements effective against the ingress of aggressive surface water protected and can, provided that the required strength is achieved, interrupted Welds are used.

The advantageous designs according to claims 18 to 20 ensure a modular Structure of the device, which is easily adaptable to the structural requirements

However, the training as described in claims 21 to 23 are also advantageous whereby to achieve a total length of the device predetermined by the roadway width Standard lengths can be manufactured and possibly only with end areas Special lengths have to be added. Furthermore, any repairs or replacements are required devices to be renewed that only affect partial areas, only a partial lock of roadways for traffic, which reduces disabilities in traffic handling become.

According to the advantageous embodiment as described in claim 24, high anchoring forces and simplified assembly.

Further advantageous developments also describe claims 25 to 28, whereby in Expansion joint area and area of the connection point to the road surface a permanent and reliable drainage of surface and leachate is given and for an ongoing Inspection and maintenance simplified conditions can be achieved.

1 is a device 1 for bridging expansion joints 2 in the course of a Roadway 3, in particular between an abutment 4, a supporting structure 5 of a bridge 6 shown.

This device 1 consists of the structure 5 of the bridge and the abutment 4 itself Direction of extension of the expansion joint 2 arranged anchor profiles 7, on which finger plates 8 with oppositely interlocking finger arrangements 9, the expansion joint 2 covering, are attached.

2 to 4, the device 1 and the attachment of the finger plates 8 on the Anchor profiles 7 shown in detail. As can be seen, the finger plates are detachably connected 8 by means of screw connections 10, formed by fastening screws 11, which with a screw shaft 12, the finger plate 8 and a base leg 13 of the anchor profiles 7 in breakthrough 14 and through fasteners 15, in particular hexagon nuts 16, under the base leg 13.

The anchor profiles 7 extend on both sides of the expansion joint 2 and are in the opposite End areas of the structures, in particular the abutment 4 and the supporting structure 5, via a Width 17 of the buildings, embedded in concrete and often interlocked connectable partial lengths. They are by a thickness 18 of the finger plates 8 compared to a surface 19 of a road surface 20 recessed base legs 13, in particular from a flat steel which runs parallel to the surface 19 and one connection bracket 21 for the road surface 20 and one in the area opposite each other End faces 22 of the abutment 4 and the structure 5 extending vertically Web plate 23 formed. The from the base leg 13, the connection bracket 21 and the Web plate 23 formed anchor profiles 7 are created in a welded construction. Furthermore are in Direction of width 17 spaced parallel to each other and at right angles to the web plate 23 welded to an underside 24 of the base leg and the connection bracket 21 Cross bars 25 are provided for stiffening, on which anchoring bracket 26 in particular are welded from reinforcing steel, on the one hand for positioning the anchor profiles 7 in a reinforcement grid 27 of the structures before casting an assembly receptacle 28 with a concrete filling 29 and anchoring in total in this concrete filling 29 serve.

Positioning means 30, which are a guide arrangement, are arranged on the underside 24 of the base legs 13 Form 31 for the hexagon nuts 16. According to preferred designs these positioning means 30 consist of a U-profile 32, which with legs 33, 34 on the underside 24 of the base leg 13 e.g. are welded by tack seams and with a The longitudinal extension is perpendicular to the web plates 23 and these in a recess 35 project through. At an opposite end region, the U-profile 32 is vertical extending leg 36 of the connecting bracket 21 connected by welding.

The positioning means 30 are in the area of the openings 14 for the fastening screws 11 and to the openings 14 with respect to a longitudinal central axis 37 extending symmetrically arranged. To form the guide arrangement 31 for the hexagon nuts 16 is an inner width 38 of the U-profile 32 slightly larger than a wrench size 39 Hexagon nut 16. A leg height 40 of the U-profile 32 is greater than a nut height 41, plus any protrusion of the fastening screw 11. An opening at the front 42 of the U-profile 32 in the region of the web plate 23 is preferably with an insertable Plastic plug 43 closed, which prevents the ingress of contaminants, Moisture concrete etc. in the positioning means 30 is effectively prevented.

The finger plates 8 are now mounted in the at least one hexagon nut 16 is inserted into the positioning means 30 and positioned with respect to the opening 14. After placing the finger plate 8 on an upper side 44 of the base leg 13, the fastening screw 11 inserted into the openings 14 and screwed to the hexagon nut 16, whereby through the formed guide arrangement 31 of the positioning means 30 a reliable protection against rotation when applying the intended torque for the Given screw 10 and accessibility for a counter tool is not required is. However, this also enables the screw connection 10 to be released later Replacing the fastening means 15 or for exchanging the finger plate 8 is that screw heads 45 in a recess 46 of the finger plate 8 and thus an upper side 47 of the finger plate 8 are not recessed in the finger plate 8. It is also mentioned that in a special embodiment the screw connections 10 for fastening the finger plates 8 in a single arrangement alternating with a pair Arrangement in the direction of the longitudinal extent of the anchor profile 7 are provided.

For positioning the hexagon nuts 16 in the guide arrangement 31 of the positioning means 30 according to a preferred embodiment, an arrangement is provided as an assembly aid, in the case of screw connections 10 arranged in pairs, two of the hexagon nuts 16 at a distance formed by a center distance 48 of the screw connections 10 49 on a carrier strip 50, e.g. made of thin sheet metal, by gluing, latching etc., are fixed and can thus be introduced in a simplified manner into the positioning means 30 and positionally assigned to the openings 14. This enables a very quick Installation, since the position of the hexagon nuts 16 exactly the hole pattern and thus the mounting screws 11 are assigned. During the fastening process, it is passed through the fastening screws 11 through the hexagon nuts 16, optionally the carrier strip 50, which is expediently provided without a bore, from the hexagon nuts 16 released and can be removed from the positioning means 30 or remain in it. It is also mentioned that even with a single screw connection 10, the application of the carrier strip 50 for positioning the hexagon nut 16 in the positioning means 30 can of course be possible and appropriate.

Another possible embodiment is the carrier strip 50 in the area of the screw passage to be provided with a bore and the hexagon nut 16 on its underside attach e.g. glue, weld, etc. The carrier strip 50, in particular if this is made of hard material, the function of an insert for pressure distribution take.

A further variant of the device 1 is shown in FIG. 5. This is the positioning device 30 for the hexagon nuts 16 of the screw connections 10 preferably by Formed tube 51 is formed, which is parallel to the underside 24 of the base leg 13 and in one Distance 52 is arranged. To achieve the distance 52, for example, between the bottom 24 of the base leg 13 and the positioning means 30, the holes 14 for the fastening screws 11 coaxially encompassing pipe sections 53 are provided. These are welded to the base leg 13 and to the shaped tube 51.

By such a configuration in which the positioning means receiving the hexagon nuts 16 30 from the base leg 13 at a distance 52 allows use longer fastening screws 11, whereby a higher degree of expansion is achieved and thus the occurring alternating loads caused by the traffic rolling over the device 1 occur, do not cause a decrease in the pretensioning force of the screw connection. This should have been a reduction in the fatigue strength of the fastening screws 11 and thus fatigue fractures result, which can be effectively avoided by these measures.

6 and 7 is another embodiment of the device 1 for fastening the finger plates 8 shown on the anchor profile 7. According to this embodiment, there is 24 on the underside of the base leg 13 of the anchor profile 7 a to the bottom 24 in a vertical direction extending molded tube section 54 is arranged with a height 55, which in an end region 56 welded to the base leg 13 and in an opposite end region 57 is provided with a cover plate 58. The positioning means 30 is reached the one box-like cavity and the guide arrangement 31 for the hexagon nut 16 trains and shields against the concrete filling 29.

In the base leg 13 of the anchor profile 7, a recess 59 is arranged, which consists of a Bore 60 and a subsequent elongated hole 61 is formed. The bore 60 points has a diameter 62 that is slightly larger than a corner dimension 63 of the hexagon nut 16. A slot width 64 of the elongated hole 61 is slightly larger than a diameter 65 Fastening screws 11. Symmetrical to a longitudinal central axis 66 of the recess 59, the shaped tube section 54 is arranged, which has an inner width 67 that is slightly is larger the wrench size 39 of the hexagon nut 16. This forms longitudinal side walls 68, 69 of the shaped tube section 59, the guide arrangement 31 and thus the anti-rotation device for the hexagon nuts 16 when applying the tightening torque to the Screw connection 10. An inner distance 70 between transverse side walls 71 is slight larger than twice the corner dimension 63 of the hexagon nut 16.

As now shown in dashed lines, the hexagon nut 16 in the Area of the bore 60 of the recess 59 inserted into the positioning means 30 and in Direction of the elongated hole 61 in a coinciding with the opening 14 in the finger plate 8 Position shifted. In this position, the mounting screws can now 11 screwed to the hexagon nut 16 and thus the finger plate 8 on the base leg 13 and thus be connected to the anchor profile 7.

According to an advantageous embodiment, the longitudinal central axis 66 of the recess is provided 59 to be arranged at an angle to the direction of the longitudinal extent of the anchor profile 7. On Angle 72 is smaller or larger than 90 °. Such an arrangement is advantageous for the paired arrangement of the screw connection 10, since a center distance of the screw connections 10 can be kept lower.

7 and also FIGS. 2 and 5 can be seen in the area of the expansion joint 2, a drainage channel 73 is provided for surface and leachate, which is preferred is formed from a channel-shaped, transparent plastic sheet 74 which is attached to the web plates 23 by means of anchoring means 75 and with which a derivative of the water in the longitudinal direction of the device 1. In order to do that in the connection area in Surface water seeping into the road surface must be recorded and discharged in the Leg 36 of the connection bracket 21 and in the web plate 23, spaced in the longitudinal direction Drainage slots 76 are provided which extend over the underside 24 of the base leg 13 arranged channels 77 are connected to the flow and thus a leachate - according Arrow 78 - the drainage channel 73 is supplied. Appropriate disposal of part aggressive water is for reasons of corrosion protection and therefore for the long service life the device 1 of special decision. It is also preferred for these reasons at least in some areas the device 1 with a coating 79, e.g. one corrosion-resistant plastic or the like.

As can further be seen from FIG. 1, a total length 80 of the device is preferred 1, which results from the width 17 for the buildings, from several sections of the Anchor profiles 7 formed with a length 81. The length 81 is expediently one Grid pitch of the screw connection 10 adapted, resulting in a modular structure and partial series production is achieved. Furthermore, the length 81 is preferably smaller or equal to half the width 17 of the building. To make the total length 80 have the anchor profiles 7 in end regions 82 connecting flanges 83 for screw connections 84 for mounting on.

The length 81 of the anchor profiles 7 is also preferably an integral multiple a width 85 of the finger plate measured in the direction of the longitudinal extent of the device 1 8 i.e. that to achieve the required total length 80 of the device 1 a A plurality of finger plates 8 are attached to the anchor profiles 7.

This means that special lengths may only be required in the peripheral areas Shortening series parts are easy to manufacture and assemble. An advantage of this training also results in the repair and, if necessary, replacement of parts of the Device 1 in the barrier to traffic required only in certain areas.

It should also be mentioned that the device 1 for bridging expansion joints 2 of course in the training according to the invention also on steel bridges and / or Steel abutment constructions can be used and compared to the Known solutions has a significantly reduced space requirement, which means that this also for the renovation of existing expansion joints - bridging devices used can be.

For the sake of order, it should finally be pointed out that for a better understanding of the Construction of the device 1, these or their components, sometimes to scale and / or were shown enlarged and / or reduced. The independent inventive one Solutions underlying the problem can be found in the description.

Above all, the individual versions shown in FIGS. 1, 2, 3, 4, 5, 6, 7 can be the subject form independent solutions according to the invention. The relevant invention Tasks and solutions are to the detailed descriptions of these figures remove.
